Depends. If you get to the Revolver tent early enough, you get a black wristband for free and he'll sign one item of your choosing. If you buy Antennas to Hell for $20 at the Slipknot tent, you get a blue wristband and a guarantee to meet three band members, but they only sign posters they already have at their tent and a security guard hands them to you - presumably to keep the line moving faster.

Free wristband it is

Actually Id like to get Corey and Kerry to sign the new Revolver cover
